Description

Electronic equipment and programs

Embodiments described herein relate generally to a portable electronic device.

In recent years, electronic devices that can be driven by a battery, such as tablet terminals and smartphones, have been widely used. Recently, electronic devices of the type that are worn on the human body, such as wristwatches and eyeglasses, such as wearable devices, have also appeared.

Many of these types of portable electronic devices have a navigation function that guides the user to the destination. Various proposals have been made regarding the navigation function.

JP 2006-275520 A

In navigation devices, first, it is common to receive a destination input from a user. However, for example, after parking a vehicle (automobile, motorcycle, bicycle, etc.) in a large parking lot or geographically unguided place and moving on foot, the vehicle is parked using the navigation function of a tablet terminal, for example. It is difficult to enter the destination accurately if you want to return to the place you did.

For example, a mechanism of a navigation function that guides the user to the place where the vehicle is parked in cooperation with the navigation device attached to the vehicle has been proposed, but without such cooperation, that is, alone to the place where the vehicle is parked There was no proposal for a mechanism of a navigation function for guiding users.

In addition, the mechanism of the navigation function that guides the user to the place where the vehicle is parked in cooperation with the navigation device attached to the vehicle, for example, when a rental car is used in a travel destination, the navigation device attached to the vehicle cooperates. If it does not have a function, the mechanism for guiding the user to the place where the vehicle is parked does not function.

According to the embodiment, the electronic device includes position detection means, acceleration detection means, estimation means, recording means, and navigation means. The estimation means estimates the movement means based on the detection value of the position detection means and the detection value of the acceleration detection means. The recording means records information on a point where the moving means estimated by the estimating means has changed. The navigation means executes a guidance process to a point indicated by information recorded in the recording means.

Hereinafter, embodiments will be described with reference to the drawings.

(First embodiment)
First, the first embodiment will be described.

The electronic device of the present embodiment can be realized as a portable electronic device that can be touch-inputted with a finger, such as a tablet terminal or a smartphone. FIG. 1 is a perspective view illustrating an appearance of an electronic apparatus according to the present embodiment. As shown in FIG. 1, it is assumed here that the electronic apparatus is realized as a tablet terminal 10. The tablet terminal 10 includes a main body 11 and a touch screen display 12. The touch screen display 12 is attached to be superposed on the upper surface of the main body 11.

The main body 11 has a thin box-shaped housing. The touch screen display 12 incorporates a flat panel display and a sensor configured to detect the ground contact position of the finger on the screen of the flat panel display. The flat panel display is, for example, a liquid crystal display (LCD). The sensor is, for example, a capacitive touch panel. The touch panel is provided so as to cover the screen of the flat panel display.

FIG. 2 is a diagram showing a system configuration related to the navigation function of the tablet terminal 10.

As shown in FIG. 2, the tablet terminal 10 includes a position detection unit 101, an acceleration detection unit 102, a storage unit 103, a moving unit estimation unit 104, a moving unit change position information storage unit 105, a current position calculation unit 106, a guidance route calculation. Unit 107, map display unit 108, user interface unit 109, display unit 110, and input unit 111.

The position detection unit 101 is a GPS (global positioning system), for example, and detects a position based on a signal received from an artificial satellite. The acceleration detection unit 102 is, for example, an acceleration sensor, and detects a speed change (per unit time) of the tablet terminal 10. The storage unit 103 is a memory device that stores various programs and various data.

The movement means estimation unit 104 estimates a movement means (for example, a vehicle, a walk or a stop) based on the detection value of the position detection unit 101 and the detection value of the acceleration detection unit 102. More specifically, the moving means is estimated from the change state (movement speed, shaking, etc.) of these two detection values. The moving speed moving unit estimation unit 104 outputs information indicating the estimation result to the moving unit change position information storage unit 105. For example, once estimating that the user is moving with the vehicle, the moving means estimation unit 104 maintains the estimation result until a stop is detected thereafter.

The moving means change position information storage unit 105 stores information (for example, the detection value and time of the position detection unit 101) regarding the point where the moving means indicated by the information input from the moving means estimation unit 104 has changed. FIG. 3 is a diagram for explaining an operating principle in which the moving unit change position information storage unit 105 stores information.

First, it is assumed that the moving means A (for example, an automobile) is estimated by the moving means estimating unit 104 (a1 in FIG. 3). After that, it is assumed that a stop is detected by the moving means estimation unit 104 (a2 in FIG. 3). When the stop is detected, the moving means estimation unit 104 estimates the moving means, but it is assumed that the moving means A is estimated next (a3 in FIG. 3).

Thereafter, similarly, every time a stop is detected, the movement means estimation unit 104 estimates the movement means. Here, the stop (a4 in FIG. 3) → the movement means B (for example, walking: a5 in FIG. 3). ) → Stop (a6 in FIG. 3) → Movement means B (a7 in FIG. 3) is assumed to be detected and estimated in this order.

At this time, the moving means change position information storage unit 105 stores information related to the point where the stop indicated by the symbol a4 is detected. In other words, the moving unit change position information storage unit 105 is a point where a stop is detected by the moving unit estimation unit 104, and the moving unit estimated by the moving unit estimation unit 104 before the detection and the moving unit estimation unit after the detection. Information on a point different from the moving means estimated by 104 is recorded. Accordingly, since the moving means estimated before and after the point where the stop indicated by reference signs a2 and a6 is detected is the same, the moving means changing position information saving unit 105 does not save the information. Note that the method of detecting the change position of the moving means by comparison between before and after the detection of the stop is merely an example, and is not limited to this, and as a method of detecting the change position of the moving means, Other approaches can be applied.

The current position calculation unit 106 calculates the current position of the user who carries the tablet terminal 10 and moves based on the detection value of the position detection unit 101 and the detection value of the acceleration detection unit 102. The guide route calculation unit 107 calculates a route from the current position calculated by the current position calculation unit 106 to a point indicated by, for example, the information stored most recently by the moving means change position information storage unit 105. The map display unit 108 displays an image (typically a map) related to the route calculated by the guide route calculation unit 107.

The moving means estimating section 104, moving means changed position information storing section 105, current position calculating section 106, guide route calculating section 107, and map display section 108 are executed by the main CPU (stored in the storage section 103). It can be realized as a program or peripheral circuit firmware.

The user interface unit 109 executes an information output process via the display unit 110 for the user regarding the navigation function and an information input process via the input unit 111 from the user regarding the navigation function. The display unit 110 is a flat panel display incorporated in the touch screen display 12 shown in FIG. 1, and the input unit 111 is a touch panel incorporated in the touch screen display 12.

The navigation function of the tablet terminal 10 may be automatically activated when the tablet terminal 10 is turned on, or may be activated in response to an instruction from the user through the user interface unit 109. When the navigation function is activated, processing such as the above-described estimation of the movement means by the movement means estimation unit 104 and storage of information by the movement unit change position information storage unit 105 are started.

When the user interface unit 109 receives a guidance request for the parking position of the vehicle, the guidance route calculation unit 107 stores a predetermined number of information stored by the moving means change position information storage unit 105 in the order of the most recent storage (for example, 2) only get. The guide route calculation unit 107 requests the map display unit 108 to display a map in which the point indicated by these pieces of information is marked as a candidate site, and the map display unit 108 displays the requested map image as a user interface unit. The information is displayed on the display unit 110 via 109. By listing several candidate locations, for example, errors in estimation by the moving means estimation unit 104 can be covered. In addition, for example, in the case of a change in moving means such as automobile → bicycle → walking, in addition to returning to the parking position of the bicycle, the user can also return directly to the parking position of the automobile. In addition, when the guidance request to the parking position of a vehicle is received, you may make it stop the process of the moving means estimation part 104 and the moving means change position information storage part 105. FIG.

The user selects one of the candidate locations indicated by the map displayed on the touch screen display 12 as the destination. This selection is performed by a touch operation on the touch screen display 12. When the user interface unit 109 receives this selection instruction, guidance processing to the parking position of the vehicle by the cooperation of the current position calculation unit 106, the guide route calculation unit 107, and the map display unit 108 is started.

That is, the current position calculation unit 106 calculates the current position of the user carrying the tablet terminal 10 and moves, the guide route calculation unit 107 calculates the route from the current position to the destination, and the map display unit 108. However, various processes such as displaying an image related to the route are started. These processes are repeated until the current position and the destination substantially match.

In the above, an example in which a plurality of candidate locations are presented when a guidance request to the parking position of the vehicle is made has been described. However, the guidance process is quickly performed with the location indicated by the most recently saved information as the destination. You may make it start. Further, after the guidance to the destination, when the guidance request to the parking position of the vehicle is made again, the guidance processing may be further started with the position indicated by the information stored immediately before the destination as the destination. Good.

FIG. 4 is a first flowchart showing a flow of operations of the navigation function of the tablet terminal 10.

The tablet terminal 10 first estimates the moving means (block A1). After estimating the moving means, the tablet terminal 10 subsequently monitors whether it is in a stopped state (block A2). If it detects that it has stopped (YES in block A2), the tablet terminal 10 again estimates the moving means (block A3).

When the moving means is estimated, the tablet terminal 10 next checks whether the moving means has changed between before the stop state is detected and after the stop state is detected (block A4). When the moving means has changed (YES in block A4), the tablet terminal 10 acquires the current position (block A5), and calculates the time when the moving means has changed (stop state detection time) and the acquired current position. Record (block A6). The tablet terminal 10 repeats the processing from the block A2 while the navigation function is operating (NO in block A7).

As described above, the tablet terminal 10 independently and automatically records information on the point where the moving means has changed.

FIG. 5 is a second flowchart showing a flow of operations of the navigation function of the tablet terminal 10.

When a guidance request to the parking position of the vehicle is made, the tablet terminal 10 searches for the previous movement means change position (B position), for example (block B1), and searches the current position (A position) (block B2). ). When these positions are searched, the tablet terminal 10 searches for a route from the A position to the B position (block B3), and displays an image related to the route (block B4). While the A position and the B position are different (NO in block B5), the tablet terminal 10 repeats the processing from the block B2.

As described above, the tablet terminal 10 realizes a navigation function mechanism that guides the user to the place where the vehicle is parked, for example, without cooperation with a navigation device associated with the vehicle.

Here, since it is assumed that the electronic device according to the present embodiment is realized as the tablet terminal 10 including the touch screen display 12, the user can display the route-related image to the place where the vehicle is parked. However, the user may be guided to the place where the vehicle is parked by outputting a sound related to the route. That is, even in an electronic device that does not have a display unit, it is possible to guide the user to the place where the vehicle is parked by voice. Further, both display of an image related to the route and output of sound related to the route may be performed.

(Second Embodiment)
Next, a second embodiment will be described.

FIG. 6 is a diagram showing a system configuration related to the navigation function of the electronic apparatus (tablet terminal 10) according to the present embodiment.

As shown in FIG. 6, the tablet terminal 10 further includes a height detection unit 112. The height detection unit 112 is, for example, an atmospheric pressure sensor. In the present embodiment, the detection value of the height detection unit 112 is included as information stored by the moving means change position information storage unit 105. The guide route calculation unit 107 also performs route calculation in consideration of the detection value of the height detection unit 112.

This makes it possible to guide the user to that level when the vehicle stops at a three-dimensional parking lot such as a building.

Since various processes of the embodiment can be realized by a computer program, the computer program is installed in a normal computer and executed through a computer-readable storage medium storing the computer program, and similar to the embodiment. The effect of can be easily realized.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
